Q. The wall of a dam is made thicker at the bottom than at the top because the pressure exerted by the water on the wall

(A) Depends on the thickness of the wall
(B) Increases with height of the wall
(C) Increases with depth of the wall
(D) Depends on the area of the wall

Correct Answer - Option(C)

Explanation by: Lokendra Rathod

The pressure applied to walls of the dam will be a function of the amount of water that is over that particular point on the wall. So water pressure is very large at the bottom due to its large depth. That's why dams are constructed thicker at their bottoms than at their tops.
